摘要： A television display apparatus (10) wherein a white light source (12) emits a beam onto a plurality of dichroic mirrors (20) which split the beam into three beams of the primary colors, then reflects the three primary beams onto three deformable reflective surfaces (44), which again reflect the beams through slits (36) in a non-reflective surface (34), thereby modulating the intensity of the beams. The amount of light passing through the slits (36) is horizontally scanned by one surface of a rotating polygonal mirror (54), then passes through collimating and projection lenses and onto a screen.

摘要： A thin film actuated mirror is disclosed having a substrate (16), a deformable structure (12) mounted to the substrate (16), and a mirror surface (17) interconnected to the deformable structure such that the mirror surface tilts in response to the deformation of the deformable material layer. The deformation occurs due to the effective strain gradient across the monomorph thickness which is accomplished by varying the electric field across the thickness or the strain parameter across the thickness. The deformable structure (12) includes an active material layer (18) fabricated from a semi-conductive ferroelectric ceramic material and two metal electrodes, each of the electrodes being mounted on opposing surfaces of the active material layer (18), wherein an electrical signal applied across the active material layer (18) between the electrodes causes deformation of the active material layer (18). Alternatively, the active material layer (18) may be fabricated from two layers, an upper layer (36) of an active piezoelectric material and a lower layer (38) of an inactive material.

摘要： A piezoeletric actuator (10) includes a pair of piezoelectric members (16a, 16b) which are oriented to shear laterally toward each other in the presence of an applied voltage. A hinge (18) having translational members (34a, 34b), which act similarly to a rack, and a rotating member (36), which acts similarly to a pinion, is attached to the top (24a, 24b) of the piezoelectric members (16a, 16b) with one translational (34a, 34b) attached to a respective one of the piezoelectric members (16a, 16b). A driven member (38) attached radially outward from the rotating member (36) will then move through an arc when the piezoelectric members (16a, 16b) laterally shear. An object, such as a mirror (12), when carried by the distal end (46) of the driven member (38), will then be actuated.

摘要： An apparatus to modulate the intensity of a pixel displayed on a screen (24) focuses optical energy from a broadbrand source (12) onto a reflective first face of a planar member (16). The first face is disposed in said first propagation path (34) at a selected angle thereto to direct optical energy along a second propagation path (40). A planar mirror (20) is disposed in the second propagation path (40). The plane of the mirror is actuatable to orientate the mirror within a range of angles to said second propagation path (40) to focus optical energy reflected from the first face onto the mirror (20).

摘要： An actuator (10) for tilting the plane of an object is constructed from a stack (16) of piezoelectric or electrostrictive members (18). First alternate interstices between the members (18) are filled with a first conductive material (20), except that a first gap remains between the material (20) and one side (26) of the stack (16). Similarly, second alternate interstices between the members (18) are filled with a second conductive material (22), except that a second gap remains between the material (22) and an opposite side (24) of the stack (16). The first gap and the second gap have unequal depth into the stack (16). The first material (20) in the first interstices is coupled in common and the second material (22) in the second interstices is coupled in common. A voltage applied between the first material (20) and the second material (22) will thereby cause the stack (16) to bend, thereby tilting the plane of the top (23) of the stack (16).

摘要： Optical energy from a broadband source (12) is focused on an aperture (30) in an opaque member (16). The energy exiting the aperture (30) is received off axis by a parabolic mirror (18) which collimates the energy. The collimated energy is reflected from each planar mirror of an actuated mirror array (20). The reflected energy from the mirror array (20) is reflected to the aperture (30) by the parabolic mirror (18). The orientation of each planar mirror determines the flux which passes through the aperture (30) or is reflected by a reflective face (28) of the opaque member (16). The energy reflected from this face (28) which is derived from each mirror corresponds to the flux intensity for a corresponding pixel. This energy may then be focused on a screen (24) to display the scene.
